Entry is now denied to people diagnosed as, "epileptics, the insane, individuals with impairments of sight, speech and sound, those with contagious diseases, as well as the destitute, impoverished and anyone likely to become a public charge." Other inadmissible immigrants include those convicted of "crimes of moral turpitude, prostitutes and anyone involved in the procurement of prostitutes."

White Canadians push to include limits on immigrants from Eastern and Southern Europe, but are not successful.
